Core Insights - The research team from the Chinese Academy of Agricultural Sciences has revealed that lignans in flaxseed significantly enhance the metabolic conversion rate of alpha-linolenic acid (ALA) into DHA and EPA, providing a new strategy for plant-based n-3 polyunsaturated fatty acids [1][3] Group 1: Research Findings - The study demonstrates that lignans, which have antioxidant properties and improve insulin resistance, can act as effective dietary modulators to increase the absorption efficiency of ALA [3] - Co-ingestion of lignans with ALA-rich flaxseed oil emulsion resulted in a 31.9% increase in serum EPA levels and a 20.2% increase in DHA levels in mice, along with a 35.1% increase in liver EPA levels [3] - Lignans also facilitate the incorporation of newly synthesized fatty acids into cell membranes and across tissue barriers, enhancing their health benefits [3] Group 2: Implications and Support - This research holds significant theoretical and industrial application value for enriching sources of long-chain n-3 polyunsaturated fatty acids and improving the nutritional value of plant-based ALA [3] - The study received funding from the National Characteristic Oilseed Industry Technology System, the National Natural Science Foundation, and innovation groups in Hubei Province [3]
